How Installing Energy-Efficient Windows in Old Westbury Saves You Money

There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 307 pounds.

Estimated Cost of Window Replacement in Old Westbury

When looking into window installation, each company provides varying services and costs. Let's go over some average costs and services.

How Much Do New Windows Cost?

Generally, Old Westbury homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at around $600. This is because the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

When considering window installations, there are typically two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you figure out what's best for your needs. In Old Westbury, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Old Westbury

EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. We've assessed the top window installation companies in Old Westbury mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, warranty, cost, quality of installation, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Old Westbury's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Old Westbury window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Old Westbury, NY Window Replacement FAQs

What is the average cost to replace windows?

The typical cost to install a single window ranges from $450 to $650. There are a variety of factors that affect the price, such as how energy-efficient the windows are, styles and sizes of windows, the number of windows, your property's location, local labor costs and the materials used in designing the windows.

What kind of window is the most energy-efficient?

A window's energy efficiency is affected by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Do you really need to use a window installation company?

You should use a window installation professional whenever you need to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation more difficult.

How often should you replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
